I have recently moved into a rented flat, and I'm trying to work out how the Siemens electric heating system works.
I have a number of Siemens electric heaters, which are each connected to a fused power switch on the wall. I also have a RWB7 timeswitch (link below) which is installed in a cupboard within the flat.

The RWB7 is currently set to 'OFF', however if I turn a heater on using the power switch on the wall, it immediately comes on and starts warming up to the temperature set using the dial on the heater itself (picture below). The right-hand red LED comes on if the heater is warming up, and off when it has reached the temperature.

What I can't work out, is what the timeswitch actually does. When the timeswitch is set to 'ON', the left-hand green LED (marked EC0) is lit. The right-hand red LED will actually also turn off(!) and the heater will stop warming up if the green LED is on, although turning up the temperature dial will cause the red LED to light up again (resulting in both LEDs being lit).
I'm a little stumped. I would have expected the heaters to only warm up when both (1) the green LED is lit - i.e. timeswitch is ON, and (2) the red LED is lit - i.e. room temperature is low enough. But this isn't the case. The red LED is lit whenever the temperature is low enough, it would seem. This causes the heater to be on despite the ON or OFF setting of the timeswitch.
Can anyone enlighten me? Below is a picture of the label on the top of the heater.
